If you live in Rowlett you will always find a coupon in your mailbox from Lone Star for $15 oil changes. It's so worth it. They are a very small establishment but they do very good work at a great price. They open very early so it's easy to stop in on your way to work to get your oil changed. The people that work there are very friendly. I will definitely continue to take my autos there and would recommend the place in a heartbeat.
